HM2P07PDM321N9LF Equivalent & Substitute Parts

Part Overview

The HM2P07PDM321N9LF is a 154-position backplane connector header manufactured by Amphenol ICC (FCI) in the Millipacs® series. This press-fit through-hole connector features 110 signal positions plus 44 dedicated ground positions arranged in a 5+2 row configuration with 2.00mm pitch. The part is currently active in production and RoHS compliant. Substitute parts may be required due to supply constraints, packaging preferences, or specific application requirements while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution logic for the HM2P07PDM321N9LF is based on the following critical parameters:

Position Configuration Match: The main part features 154 total positions (110 signal + 44 ground) in a 5+2 row arrangement. Substitute parts must maintain this exact position count and row configuration to ensure PCB footprint compatibility and signal integrity.

Electrical Specifications: Current rating (1.5 A minimum), voltage rating (minimum 500Vrms), and operating temperature range (-55°C to 125°C) define the electrical envelope. Parts meeting or exceeding these specifications are compatible.

Mechanical Compatibility: Pitch (2.00mm), connector style (A 22), mounting type (through hole), and termination method (press-fit) must remain constant across all substitutes.

Compliance Requirements: RoHS compliance status and MSL rating (1 - Unlimited) are mandatory for equivalent substitution.

Substitute parts are grouped into two categories:

Category A - Full Position Match (154 positions): PCN21B-110PB-2PF-G maintains the complete 154-position configuration with identical row structure.

Category B - Reduced Position Match (110 positions): HARTING 17011102201, 17011102204, 17011102402 and TE Connectivity 5100143-1 provide 110-position headers. These are suitable only when application requirements permit elimination of dedicated ground positions or when ground distribution is handled through alternative means.

Engineering Selection Recommendations

For Direct Footprint Replacement: PCN21B-110PB-2PF-G is the only substitute maintaining the complete 154-position configuration with 5+2 row structure. However, this part carries obsolete product status and should be selected only when existing PCB designs cannot be modified. Voltage rating (300V) is lower than the main part (750Vrms) and must be verified against application requirements.

For 110-Position Applications: HARTING parts (17011102201, 17011102204, 17011102402) and TE Connectivity 5100143-1 are suitable when application design permits elimination of dedicated ground positions. These parts are all active in production status. TE Connectivity 5100143-1 matches the main part's 1.5A current rating and provides superior voltage rating (500Vrms) compared to HARTING alternatives (1.0A current rating, unspecified voltage). HARTING parts offer ROHS3 compliance and are available in higher quantities.

Compliance Considerations: All substitute parts maintain RoHS compliance and MSL 1 (Unlimited) moisture sensitivity rating. HARTING parts include REACH Unaffected status documentation. TE Connectivity 5100143-1 shows REACH status as Vendor Undefined and should be verified for specific regulatory requirements.

Packaging and Availability: HARTING parts are supplied in tube packaging with higher inventory levels (885–1900 pcs). TE Connectivity 5100143-1 offers the highest inventory (3040 pcs) in tube packaging. PCN21B-110PB-2PF-G is supplied in bulk packaging with 1117 pcs available.

Frequently Asked Questions (FAQ)

Q: Can HARTING 17011102201, 17011102204, or 17011102402 be used as direct replacements for HM2P07PDM321N9LF?

A: These parts are not direct replacements. They provide 110 positions in a 5-row configuration versus the main part's 154 positions (110+44 ground) in a 5+2 row arrangement. PCB footprint compatibility cannot be assumed. Use these parts only when application design explicitly permits 110-position headers without dedicated ground rows.

Q: What is the difference between HARTING 17011102201, 17011102204, and 17011102402?

A: All three parts share identical electrical and mechanical specifications: 110 positions, 2.00mm pitch, 5 rows, press-fit termination, 1.0A current rating, and -55°C to 125°C operating temperature. Differences are limited to contact finish options (Gold or Gold-Palladium) and internal design variants not specified in available documentation. Selection between these parts should be based on inventory availability and packaging preferences.

Q: Is TE Connectivity 5100143-1 compatible with the main part's voltage requirements?

A: TE Connectivity 5100143-1 is rated for 500Vrms, which is lower than the main part's 750Vrms rating. This part is suitable only for applications where 500Vrms voltage rating meets design specifications. Verify application voltage requirements before selection.

Q: Why is PCN21B-110PB-2PF-G marked as obsolete?

A: PCN21B-110PB-2PF-G carries obsolete product status from Hirose Electric. While this part maintains the 154-position configuration and is currently in stock (1117 pcs), it should be selected only when existing designs cannot accommodate active alternatives. Future availability cannot be guaranteed.

Q: What are the key differences in current rating between substitute parts?

A: The main part HM2P07PDM321N9LF and TE Connectivity 5100143-1 are both rated for 1.5A. HARTING parts (17011102201, 17011102204, 17011102402) are rated for 1.0A. PCN21B-110PB-2PF-G is rated for 1.5A. Applications requiring 1.5A current capacity must use either the main part, TE Connectivity 5100143-1, or PCN21B-110PB-2PF-G.

Q: Are all substitute parts RoHS compliant?

A: Yes. The main part is RoHS Compliant. All substitute parts carry either RoHS Compliant or ROHS3 Compliant status, meeting current regulatory requirements. HARTING parts additionally document REACH Unaffected status.

Q: What packaging options are available for these parts?

A: HM2P07PDM321N9LF is supplied in trays. HARTING parts and TE Connectivity 5100143-1 are supplied in tubes. PCN21B-110PB-2PF-G is supplied in bulk packaging. Packaging selection may affect handling, storage, and assembly processes.
