Substitute Part Grouping Explanation

Substitute parts for the M22-5320246P are identified based on strict electrical and mechanical parameter alignment. The primary substitution criteria are:

Pitch - Mating: 0.079" (2.00mm) — exact match required
Number of Positions: 4 — exact match required
Number of Rows: 2 — exact match required
Row Spacing - Mating: 0.079" (2.00mm) — exact match required
Mounting Type: Surface Mount — exact match required
Termination: Solder — exact match required
Contact Type: Male Pin — exact match required
Operating Temperature Range: -40°C ~ 105°C — minimum requirement
Material Flammability Rating: UL94 V-0 — minimum requirement
RoHS Status: ROHS3 Compliant — regulatory requirement

Two substitute parts meet these criteria: M22-5320246 (Harwin Inc., active status) and NRPN022MAMS-RC (Sullins Connector Solutions, active status). Both maintain full electrical and mechanical compatibility with the original M22-5320246P specification.

Engineering Selection Recommendations

M22-5320246 is the primary substitute for M22-5320246P. Both parts are manufactured by Harwin Inc. within the same M22 series, share identical electrical and mechanical specifications, and maintain full compatibility. The M22-5320246 holds active product status, ensuring long-term availability and supply chain continuity. This part is recommended as the direct replacement for obsolete M22-5320246P applications.

NRPN022MAMS-RC from Sullins Connector Solutions serves as an alternative substitute. This part maintains all critical electrical and mechanical parameters required for functional equivalence, including pitch, position count, row spacing, mounting type, and operating temperature range. The NRPN022MAMS-RC features gold-plated contacts with higher current rating (2A versus 1A per contact) and brass contact material, providing enhanced performance characteristics. This part is suitable for applications where increased current capacity or superior contact reliability is beneficial. Both substitute parts carry ROHS3 compliance and MSL 1 rating, meeting regulatory and environmental requirements.

Frequently Asked Questions (FAQ)

Q: Can M22-5320246 be used as a direct replacement for M22-5320246P?

A: Yes. M22-5320246 is electrically and mechanically identical to M22-5320246P. Both parts share the same pitch (2.00mm), position count (4), row spacing (2.00mm), mounting type (surface mount), and operating temperature range (-40°C ~ 105°C). The primary difference is product status: M22-5320246P is obsolete while M22-5320246 is active.

Q: What are the differences between M22-5320246 and NRPN022MAMS-RC?

A: Both parts are functionally equivalent for standard applications. Key differences include: contact finish (tin versus gold), contact material (phosphor bronze versus brass), current rating (1A per contact versus 2A), and contact length mating (4.60mm versus 3.60mm). NRPN022MAMS-RC provides higher current capacity and gold plating for enhanced corrosion resistance.

Q: Are there voltage rating differences between these parts?

A: Voltage rating is not specified for M22-5320246P or M22-5320246. NRPN022MAMS-RC specifies 150V. For applications requiring voltage rating confirmation, consult manufacturer datasheets.

Q: Do packaging differences affect compatibility?

A: Packaging (bulk for M22-5320246, tube for NRPN022MAMS-RC) affects procurement and handling but does not affect electrical or mechanical compatibility. Select packaging based on assembly process requirements and inventory management practices.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. M22-5320246, M22-5320246P, and NRPN022MAMS-RC are all ROHS3 compliant with MSL 1 (unlimited moisture sensitivity level).
