PCE-C-12 Equivalent & Substitute Parts

Part Overview

The PCE-C-12 is a 12-position receptacle connector with bottom entry configuration, 0.100" (2.54mm) pitch, designed for through-hole solder termination. This connector is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and component procurement. The part features board hooks for mechanical retention and is rated for 3A at 250VAC across automotive, general purpose, medical, and telecommunications applications.

Substitute Part Grouping Explanation

Substitution eligibility for the PCE-C-12 is determined by the following critical parameters:

Connector Configuration: Receptacle, bottom entry, 12-position
Pitch Specification: 0.100" (2.54mm) mating pitch
Mounting & Termination: Through-hole solder termination
Mechanical Interface: Push-pull fastening with board hooks
Electrical Performance: Contact finish (tin), voltage rating (250VAC), and current capacity
Environmental Compliance: UL94 V-0 flammability rating, RoHS3 compliance

The substitute part 0022142124 (Molex KK254/4455 series) meets these core substitution criteria. Both parts share identical connector type, position count, pitch, mounting method, and termination approach. Compliance certifications (UL94 V-0, RoHS3) are equivalent.

Engineering Selection Recommendations

The Molex 0022142124 connector is functionally equivalent to the PCE-C-12 for applications where the following conditions are met:

Current Requirements: Application current demand does not exceed 2.5A. The PCE-C-12 is rated for 3A; the Molex substitute is rated for 2.5A.
Temperature Environment: Operating temperature range remains within -40°C to 80°C. The PCE-C-12 supports -40°C to 105°C; the Molex part has a narrower upper limit.
Physical Constraints: PCB layout accommodates the Molex insulation height of 0.311" (7.90mm) versus the PCE-C-12 height of 0.276" (7.00mm). Contact post length difference (0.146" vs. 0.132") must be verified against mating connector depth requirements.
Compliance Requirements: Both parts meet UL94 V-0 flammability and RoHS3 compliance standards.

The Molex part carries active product status, ensuring ongoing availability and supply chain support compared to the obsolete PCE-C-12.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0022142124 directly replace the PCE-C-12 in existing designs?

A: Direct replacement is possible if application current does not exceed 2.5A and operating temperature remains below 80°C. Physical dimensions (insulation height and contact post length) must be verified against PCB layout and mating connector specifications.

Q: What is the primary difference in electrical performance between these connectors?

A: The PCE-C-12 is rated for 3A at 250VAC with an operating temperature range of -40°C to 105°C. The Molex 0022142124 is rated for 2.5A at 250VAC with an operating temperature range of -40°C to 80°C. Both maintain 250VAC voltage rating and UL94 V-0 compliance.

Q: Are there material differences between the two connectors?

A: Yes. The PCE-C-12 uses phosphor bronze contacts, while the Molex 0022142124 uses brass contacts. Both insulators are polyamide-based (nylon). These material differences do not affect functional compatibility for standard board-to-board or cable applications within the specified electrical and thermal parameters.

Q: What packaging format is the Molex substitute supplied in?

A: The Molex 0022142124 is supplied in tray packaging, compared to the PCE-C-12 which has no specified packaging format listed.

Q: Are both connectors RoHS compliant?

A: Yes. Both the PCE-C-12 and Molex 0022142124 are ROHS3 compliant and REACH unaffected.
