Parameter Comparison

Engineering Selection Recommendations

The POM-2742P-2-R is the qualified substitute for the obsolete POM-2742P-2. Selection of the substitute part is based on the following engineering criteria:

Product Status: The POM-2742P-2-R maintains active product status, ensuring ongoing availability and manufacturer support. The original POM-2742P-2 is obsolete and subject to supply discontinuation.

Regulatory Compliance: The POM-2742P-2-R achieves ROHS3 compliance, meeting current environmental and material restriction requirements. The original part is RoHS non-compliant and may not satisfy procurement or regulatory requirements for new designs or production batches.

Electrical Performance: Both parts maintain identical electrical specifications across sensitivity, impedance, voltage range, and supply current parameters, ensuring functional equivalence in circuit applications.

Physical Compatibility: The substitute part exhibits a maximum height of 0.126" (3.20mm) compared to 0.114" (2.90mm) for the original. This 0.012" (0.30mm) dimensional variance must be evaluated within the mechanical constraints of the target application to confirm board-level and enclosure compatibility.

Frequently Asked Questions (FAQ)

Q: Can the POM-2742P-2-R be used as a direct replacement for the POM-2742P-2?

A: Yes. The POM-2742P-2-R qualifies as a direct electrical and functional substitute. Both parts share identical sensitivity (-42dB ±3dB), impedance (2.2 kOhms), voltage range (2 V ~ 10 V), and termination configuration (PC Pins). Physical compatibility must be confirmed based on the 0.012" height difference.

Q: What is the significance of the height difference between these parts?

A: The POM-2742P-2-R has a maximum height of 0.126" (3.20mm) versus 0.114" (2.90mm) for the POM-2742P-2. This 0.012" (0.30mm) increase must be evaluated against available board clearance, enclosure depth, and mechanical assembly constraints in the target application.

Q: Why is the POM-2742P-2 listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued active production and support for this part number. The POM-2742P-2-R represents the current active equivalent within the POM series.

Q: Does the substitute part meet current regulatory requirements?

A: Yes. The POM-2742P-2-R is ROHS3 compliant and REACH unaffected, meeting current environmental and material restriction standards. The original POM-2742P-2 is RoHS non-compliant.

Q: Are there any differences in frequency response between these parts?

A: The POM-2742P-2-R specifies a frequency range of 50 Hz ~ 16 kHz. The original POM-2742P-2 does not provide a frequency range specification in available documentation.

Q: What packaging options are available?

A: The POM-2742P-2 is available in standard packaging. The POM-2742P-2-R is supplied in bulk packaging format.
