The Harwin Inc. M22-5320405 meets all mandatory matching parameters and qualifies as a direct substitute for the WR-PHD 62100821921 in board-to-board connector applications requiring 8-position, dual-row, 2.00mm pitch surface mount headers with push-pull fastening and gold-plated contacts.

Parameter Comparison

Engineering Selection Recommendations

Both the WR-PHD 62100821921 and M22-5320405 are Active product status components with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1), qualifying them for equivalent use in board-to-board connector applications. The primary electrical and mechanical parameters align across pitch, row configuration, contact type, mounting method, and operating temperature range.

The WR-PHD 62100821921 specifies a current rating of 2A with 200VAC voltage rating, while the M22-5320405 specifies 1A per contact with no voltage rating provided. Applications requiring the full 2A current capacity or 200VAC voltage specification should prioritize the WR-PHD 62100821921. The M22-5320405 features a cuttable header design and is available in bulk packaging, offering flexibility for applications where individual position configuration is required.

Contact length differences exist between the parts: the WR-PHD 62100821921 provides 0.157" (4.00mm) mating contact length compared to 0.138" (3.50mm) for the M22-5320405. Insulation height also differs: 0.079" (2.00mm) for the WR-PHD versus 0.059" (1.50mm) for the M22-5320405. These dimensional variations require verification against specific PCB layout and mating connector specifications before substitution.

Frequently Asked Questions (FAQ)

Q: Can the M22-5320405 directly replace the WR-PHD 62100821921 in all applications?

A: The M22-5320405 qualifies as a substitute based on matching pitch, row configuration, contact type, mounting method, and operating temperature range. However, applications with current requirements exceeding 1A per contact or requiring 200VAC voltage rating should use the WR-PHD 62100821921. Contact length and insulation height differences must be evaluated against specific PCB layout requirements.

Q: What are the key dimensional differences between these parts?

A: The WR-PHD 62100821921 provides 0.157" (4.00mm) contact length and 0.079" (2.00mm) insulation height. The M22-5320405 provides 0.138" (3.50mm) contact length and 0.059" (1.50mm) insulation height. These differences affect mating depth and board-to-board spacing calculations.

Q: Are both parts RoHS3 compliant?

A: Yes, both the WR-PHD 62100821921 and M22-5320405 are ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Q: What is the difference in packaging between these parts?

A: The WR-PHD 62100821921 is supplied in tube packaging, while the M22-5320405 is supplied in bulk packaging. The M22-5320405 also features a cuttable header design, allowing individual position configuration.

Q: What contact materials are used in each part?

A: The WR-PHD 62100821921 uses copper alloy contacts, while the M22-5320405 uses phosphor bronze contacts. Both feature gold plating on the mating surface.

Q: Do both parts support the same operating temperature range?

A: Yes, both parts operate across the -40°C to 105°C temperature range.

Q: What is the current rating difference between these parts?

A: The WR-PHD 62100821921 is rated for 2A total current, while the M22-5320405 is rated for 1A per contact. Applications requiring higher current capacity should use the WR-PHD 62100821921.
