FFF CompatibilityFeatures the identical cylinder package, 1/8-27 NPT port, and 2-foot Belden #8444 cable termination, providing a direct drop-in mechanical mounting.Shares the same stainless-steel cylinder enclosure and 1/8" NPT port thread style as the original sensor.Provides an amplified 0.5V to 4.5V output (at 5V supply) rather than the unamplified ratiometric 0 mV to 100 mV output, requiring different signal conditioning or ADC scaling.Utilizes the exact same mechanical package, 1/8-27 NPT pressure port, and 2-foot cable with the same wire color color-coding.Shares the identical stainless-steel cylinder body and thread configuration.Designed for a much higher operating pressure range (1000 PSI instead of 100 PSI), resulting in a lower output sensitivity of 0.1 mV/PSI instead of 1.0 mV/PSI.
AI Summary

M3421-000006-100PG by TE Connectivity Measurement Specialties: Pressure Sensor 100PSI (689.48kPa) Vented Gauge Male - 1/8" (3.18mm) NPT 0 mV ~ 100 mV (5V) Cylinder.

This is a same-series sibling from the MSP340 family, offering the exact same physical package, 1/8\" NPT pressure port, and 2-foot cable. The key difference is the amplified 0.5 to 4.5 V output, which simplifies integration with standard microcontrollers but requires a higher minimum supply voltage (4.75V to 5.25V).

  • Identical physical dimensions and cylinder design
  • Same 1/8" NPT pressure port and 2-foot cable termination
  • Same 100 PSI operating range and vented gauge reference
  • Requires a 4.75V to 5.25V supply voltage (original can operate down to 2.5V)
  • Different output signal level (0.5V to 4.5V vs 0 mV to 100 mV) requires modifying the receiver/ADC circuit scaling

This is a same-series sibling from the MSP340 family featuring identical physical packaging and unamplified 0-100mV electrical interface. However, it is rated for a 1000 PSI operating range instead of 100 PSI, which reduces measurement sensitivity but provides an extremely high overpressure margin.

  • Identical unamplified 0 to 100 mV ratiometric output format
  • Same 1/8" NPT pressure port and 2-foot cable termination
  • Same electrical supply range (2.5V to 12V)
  • Lower resolution and sensitivity (0.1 mV/PSI vs 1.0 mV/PSI) when measuring pressures under 100 PSI
  • Higher full-scale rating of 1000 PSI may require external signal amplification to restore original scaling in 100 PSI systems

You searched one part. Parter watches your whole BOM.

  1. All your BOM, at once

    Parter maps every line to live stock, lead time, lifecycle and compliance data across the entire market — not part by part.

  2. Hear about problems before they hit production

    Allocation, EOL and last-time-buy notices surface the moment they appear, not when your buyer's PO bounces.

  3. Qualified replacements in minutes, not days

    Every at-risk line gets form-fit-function matches like the ones above — deltas flagged, evidence attached. Review, push to your BOM, and Parter starts watching the new part too.
