Engineering Selection Recommendations
Primary Substitutes (Direct Replacement - No Design Modification Required):
NRPN111PARN-RC and TMM-111-01-F-S-RA are functionally equivalent to M22-2531146 with all critical parameters matching. Both are active products with ROHS3 compliance. NRPN111PARN-RC maintains identical position count and loading configuration. TMM-111-01-F-S-RA provides extended operating temperature range (-55°C to 125°C versus -40°C to 105°C) and higher current rating (3.2A per contact versus 1A per contact), making it suitable for applications requiring enhanced thermal or electrical performance.
Secondary Substitutes (Mechanical Compatibility with Position Loading Variation):
TMM-111-01-F-S-RA-001 through TMM-111-01-F-S-RA-007 are Samtec variants with 10 positions loaded instead of 11. These parts maintain all critical mechanical and electrical parameters but require design verification to confirm that the single unloaded position does not impact circuit functionality. These variants offer the same performance advantages as TMM-111-01-F-S-RA with extended temperature range and higher current capacity.
Functional Alternative (Design Modification Required):
M22-2531405 is a Harwin product with 14 positions instead of 11, maintaining the same 2.00mm pitch and right-angle through-hole configuration. This part is suitable only for applications where the additional three positions can be utilized or left unconnected without affecting board layout or electrical performance. This option provides continuity within the Harwin M22 series for designs that can accommodate the increased connector footprint.
Frequently Asked Questions (FAQ)
Q: Can NRPN111PARN-RC be used as a direct replacement for M22-2531146?
A: Yes. NRPN111PARN-RC maintains all critical electrical and mechanical parameters: 11 positions, 2.00mm pitch, through-hole right-angle mounting, solder termination, and square contact geometry. The part is active and ROHS3 compliant. Minor differences include gold contact finish (versus tin) and brass contact material (versus phosphor bronze), both acceptable for standard board-to-board applications.
Q: What is the difference between TMM-111-01-F-S-RA and the TMM-111-01-F-S-RA-001 through -007 variants?
A: TMM-111-01-F-S-RA has all 11 positions loaded. TMM-111-01-F-S-RA-001 through -007 have 10 positions loaded with one position unloaded. All variants share identical electrical and mechanical specifications including extended operating temperature (-55°C to 125°C) and higher current rating (3.2A per contact). Selection depends on whether the design requires all 11 positions or can function with 10 loaded positions.
Q: Why does M22-2531405 have 14 positions instead of 11?
A: M22-2531405 is a different connector variant within the Harwin M22 series designed for applications requiring 14 connection points at 2.00mm pitch. It is not a direct replacement but a functional alternative for designs that can accommodate the increased position count and corresponding PCB footprint.
Q: Are there any thermal or electrical performance differences between the substitutes?
A: Yes. TMM-111-01-F-S-RA and its variants (TMM-111-01-F-S-RA-001 through -007) offer extended operating temperature range (-55°C to 125°C versus -40°C to 105°C) and higher current rating (3.2A per contact versus 1A per contact). NRPN111PARN-RC provides 2A current rating with 150V voltage specification. These enhancements make Samtec and Sullins options suitable for higher-performance applications.
Q: What is the significance of the contact finish difference (Tin versus Gold)?
A: Contact finish affects corrosion resistance and mating force characteristics. Gold finish provides superior corrosion resistance and lower contact resistance, particularly in humid or corrosive environments. Tin finish is acceptable for standard indoor applications with controlled environmental conditions. Both finishes are compatible with standard PCB assembly processes.
Q: Are all substitute parts ROHS3 compliant?
A: Yes. All substitute parts listed—NRPN111PARN-RC, TMM-111-01-F-S-RA, TMM-111-01-F-S-RA-001 through -007, and M22-2531405—are ROHS3 compliant, meeting regulatory requirements for hazardous substance restrictions.
Q: Can I use a substitute part with different insulation material (LCP versus Polyamide)?
A: Yes. Liquid Crystal Polymer (LCP) and Polyamide (PA6T/Nylon 6T) are both acceptable insulation materials for this connector category. LCP offers superior dimensional stability and lower moisture absorption, making it suitable for high-reliability applications. Polyamide is standard for general-purpose applications. Both materials meet UL94 V-0 flammability requirements where specified.
Q: What inventory considerations should I account for when selecting a substitute?
A: Current inventory levels are: M22-2531146 (639 pcs), M22-2531405 (817 pcs), NRPN111PARN-RC (1062 pcs), TMM-111-01-F-S-RA (636 pcs), and TMM-111-01-F-S-RA-001 through -007 (702-1129 pcs each). Samtec variants offer the highest inventory availability, followed by Sullins and Harwin options.
