Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Fully Compatible):

The following parts are direct functional equivalents to the TE Connectivity 5100145-9:

HM2R02PA5100N9LF (Amphenol ICC) and HM2R02PA5108N9LF (Amphenol ICC) meet or exceed all electrical and mechanical specifications. Both parts feature identical position count, pitch, mounting configuration, and termination method. The Amphenol parts provide superior voltage rating (750Vrms versus 500Vrms) and maintain equivalent current rating (1.5 A). Both are RoHS Compliant with MSL 1 rating. HM2R02PA5108N9LF includes upper shield feature. Amphenol parts are available in higher quantities (2024 and 10300 units respectively).

HM2R65PA5100N9LF (Amphenol ICC) is functionally equivalent with connector style AB 25 instead of B 25. This part maintains all critical electrical parameters and mechanical mounting specifications. Voltage rating is superior at 750Vrms. RoHS Compliant with MSL 1 rating. Available inventory: 1891 units.

Conditional Substitute (Current Rating Limitation):

17221251101 (HARTING) matches mechanical specifications and operating temperature range. However, current rating is 1.0 A, which is lower than the TE Connectivity part specification of 1.5 A. Voltage rating is not specified. This part is suitable only for applications where current requirements do not exceed 1.0 A. ROHS3 Compliant with MSL 1 rating. Available inventory: 1011 units.

Non-Substitutable Variant:

HM2R65PA5108N9LF features 150 positions (125 + 25 ground) with 5 + 1 rows, making it incompatible with the 125-position, 5-row requirement of the TE Connectivity 5100145-9.

Frequently Asked Questions (FAQ)

Q: Can HM2R02PA5100N9LF be used as a direct replacement for 5100145-9?

A: Yes. HM2R02PA5100N9LF is a direct functional equivalent. Both connectors share identical position count (125), pitch (2.00mm), row configuration (5), mounting type (board edge through-hole right angle), and termination method (press-fit). The Amphenol part provides equal current rating (1.5 A) and superior voltage rating (750Vrms versus 500Vrms). Both are RoHS Compliant with MSL 1 rating.

Q: What is the difference between HM2R02PA5100N9LF and HM2R02PA5108N9LF?

A: Both parts are electrically and mechanically identical with respect to position count, pitch, mounting, and termination. The primary difference is that HM2R02PA5108N9LF includes an upper shield feature, while HM2R02PA5100N9LF does not. Selection depends on electromagnetic shielding requirements for the application.

Q: Why is 17221251101 (HARTING) listed as a substitute if it has lower current rating?

A: The HARTING part meets all mechanical and thermal specifications but has a reduced current rating of 1.0 A compared to 1.5 A for the TE Connectivity part. It is listed as a conditional substitute suitable only for applications where current requirements do not exceed 1.0 A. Voltage rating for this part is not specified in available documentation.

Q: Can HM2R65PA5100N9LF be used instead of 5100145-9?

A: Yes, with connector style consideration. HM2R65PA5100N9LF has connector style AB 25 instead of B 25, but maintains all critical electrical parameters (1.5 A current, 750Vrms voltage) and mechanical specifications (125 positions, 2.00mm pitch, 5 rows, board edge through-hole right angle mounting, press-fit termination). The style difference indicates mechanical keying variation but does not affect functional compatibility in backplane applications.

Q: Why is HM2R65PA5108N9LF not a suitable substitute?

A: HM2R65PA5108N9LF is not a direct substitute because it features 150 positions (125 + 25 ground) with 5 + 1 row configuration, whereas the TE Connectivity 5100145-9 has 125 positions with 5 rows. The additional ground row and increased position count make this part incompatible with applications designed for the 125-position connector.

Q: What is the significance of packaging format (Tube versus Tray)?

A: Packaging format does not affect electrical or mechanical function. The TE Connectivity 5100145-9 is supplied in Tube packaging, while Amphenol substitutes are supplied in Tray packaging. Selection between tube and tray packaging depends on handling, storage, and assembly process requirements rather than connector performance.

Q: Are all substitute parts RoHS Compliant?

A: Yes. The TE Connectivity 5100145-9 is RoHS Compliant. All listed substitutes (HM2R02PA5100N9LF, HM2R02PA5108N9LF, HM2R65PA5100N9LF, and 17221251101) are RoHS Compliant or ROHS3 Compliant, meeting environmental regulatory requirements.

Q: What does MSL 1 (Unlimited) mean for these connectors?

A: Moisture Sensitivity Level 1 (Unlimited) indicates that these connectors have no moisture sensitivity restrictions. They can be stored and handled without special moisture control measures, simplifying logistics and inventory management compared to higher MSL rated components.
