PCN21B-95PB-2PF Equivalent & Substitute Parts

Part Overview

The PCN21B-95PB-2PF is a 95-position header connector manufactured by Hirose Electric Co Ltd, designed for backplane applications with 2.00mm pitch and press-fit termination. This connector features male pins, through-hole mounting, and gold-plated contacts rated for 1.5A at 300V across an operating temperature range of -55°C to 125°C.

The PCN21B-95PB-2PF is classified as obsolete. Equivalent and substitute connectors from active manufacturers provide direct functional replacement while maintaining electrical and mechanical compatibility for new designs and legacy system upgrades.

Substitute Part Grouping Explanation

Substitution for the PCN21B-95PB-2PF is determined by the following critical parameters:

Position Count: 95 positions (primary criterion)
Pitch: 0.079" (2.00mm) spacing
Connector Style: Header, male pins
Mounting: Through-hole, press-fit termination
Contact Material: Gold plating
Electrical Ratings: Minimum 1.5A current capacity and voltage compatibility
Temperature Range: -55°C to 125°C operation

Substitute parts are grouped into two categories:

Category A – Direct 95-Position Equivalents: Parts with identical 95-position configuration, 5-row layout, and matching electrical specifications. These provide pin-for-pin compatibility.

Category B – Extended Position Variants: Parts with 127 or 133 positions (95 signal + additional ground pins). These offer enhanced grounding but require PCB layout accommodation for additional pins.

Engineering Selection Recommendations

For Direct Replacement (95-Position, 5-Row Configuration)

HM2P71PD5110N9LF from Amphenol ICC (FCI) provides the closest functional equivalent to PCN21B-95PB-2PF. Both maintain identical connector style (B 19), 95-position count, 5-row layout, and 2.00mm pitch. The HM2P71PD5110N9LF is active in production, RoHS compliant, and rated for 750Vrms (exceeding the original 300V specification). Current rating matches at 1.5A with identical operating temperature range.

HM2P67PD5110N9LF and HM2P67PDE120N9LF from Amphenol ICC (FCI) offer equivalent electrical and mechanical specifications with connector style AB 19. Both are active, RoHS compliant, and suitable for direct substitution where connector style variation is acceptable.

CP2-HAB095-GE1-KR from 3M provides an active alternative with matching 95-position, 5-row configuration and 2.00mm pitch. RoHS compliance is confirmed. Voltage and current ratings are not specified in available documentation.

For Applications Requiring Enhanced Grounding

HM2P67PD5111N9LF, HM2P67PK5111GFLF, HM2P67PMA3T4GFLF, and HM2P71PD5111N9LF provide 127 or 133-position configurations with additional dedicated ground pins (32 or 38 ground positions respectively). These variants maintain 2.00mm pitch and 1.5A current rating but require PCB layout modification to accommodate the additional rows. Selection between 127-position (AB 19 style) and 133-position (B 19 style) depends on connector style compatibility requirements.

All Amphenol ICC (FCI) Millipacs® substitutes carry RoHS compliance and REACH affected status, suitable for modern design requirements.

Frequently Asked Questions (FAQ)

Q: Can HM2P71PD5110N9LF directly replace PCN21B-95PB-2PF without PCB modification?

A: Yes. Both connectors maintain 95 positions, 5 rows, 2.00mm pitch, and through-hole press-fit termination. The connector style designation differs (B 19 vs. B 19), but electrical and mechanical compatibility is maintained. The higher voltage rating (750Vrms vs. 300V) provides additional margin.

Q: What is the difference between 95-position and 127-position variants?

A: The 95-position configuration provides signal pins only. The 127-position variant (HM2P67PD5111N9LF, HM2P67PK5111GFLF) adds 32 dedicated ground pins across two additional rows, totaling 127 positions. The 133-position variant (HM2P71PD5111N9LF) adds 38 ground pins. Extended variants require PCB layout accommodation for additional rows but provide enhanced grounding capability.

Q: Are all substitute parts RoHS compliant?

A: All Amphenol ICC (FCI) Millipacs® substitutes listed are RoHS compliant. CP2-HAB095-GE1-KR from 3M is confirmed RoHS compliant. The original PCN21B-95PB-2PF RoHS status is not specified.

Q: What is the difference between connector styles AB 19 and B 19?

A: Connector style designations indicate physical and electrical configuration differences. Both styles maintain 2.00mm pitch and 95-position count but differ in keying and mechanical interface details. Style B 19 (HM2P71PD5110N9LF) matches the original PCN21B-95PB-2PF style. Style AB 19 variants (HM2P67 series) are functionally equivalent but require verification of mechanical compatibility in the target application.

Q: Do all substitutes support the same current and voltage ratings?

A: The original PCN21B-95PB-2PF is rated 1.5A at 300V. All Amphenol ICC (FCI) substitutes maintain 1.5A current rating but are rated for 750Vrms, providing higher voltage margin. CP2-HAB095-GE1-KR voltage and current ratings are not specified in available data.

Q: What packaging options are available?

A: Amphenol ICC (FCI) Millipacs® substitutes are supplied in tray packaging. 3M CP2-HAB095-GE1-KR is supplied in bulk packaging. Original PCN21B-95PB-2PF packaging is not specified.

Q: Are there REACH or ECCN compliance considerations?

A: All listed substitutes carry ECCN EAR99 classification. Amphenol ICC (FCI) Millipacs® variants are REACH affected. The original PCN21B-95PB-2PF is REACH unaffected. Compliance verification is required for applications subject to REACH regulations.
