Key Parameters

Substitute Part Grouping Explanation

The substitute part 5650921-5 (TE Connectivity AMP Connectors) qualifies as a functional equivalent based on the following critical parameters:

• Connector Configuration: Both parts are 120-position DIN plug connectors with male pins
• Physical Layout: Identical 3-row arrangement with 0.100" (2.54mm) pitch and Style R configuration
• Mounting & Termination: Both utilize through-hole mounting with press-fit termination
• Contact System: Gold-plated contacts on both parts
• Operating Environment: Matching temperature range of -55°C to 125°C
• Insulation Material: Both employ glass-filled thermoplastic insulation with UL94 V-0 flammability rating
• Moisture Sensitivity: Both rated MSL 1 (Unlimited)

The substitute part is currently in active production status with improved RoHS3 compliance, addressing the non-compliant status of the original part.

Engineering Selection Recommendations

The 5650921-5 serves as a direct functional substitute for the obsolete DIN-120RPC-DPS-TR. Selection of this alternative is supported by:

• Electrical Compatibility: Identical pin configuration, pitch, and contact system ensure direct PCB compatibility
• Mechanical Fit: Matching mounting type and connector geometry allow direct board-level replacement
• Environmental Performance: Equivalent operating temperature range and moisture sensitivity rating maintain system reliability across specified conditions
• Regulatory Compliance: The substitute part achieves ROHS3 compliance, addressing regulatory requirements that may apply to new designs or system updates
• Production Status: Active manufacturing status of the substitute part ensures long-term availability and supply chain stability

Frequently Asked Questions (FAQ)

Q: Can the 5650921-5 be used as a direct replacement on existing PCBs designed for the DIN-120RPC-DPS-TR?

A: Yes. Both connectors share identical pitch (0.100"), row configuration (3 rows), position count (120), and mounting type (through-hole press-fit). PCB footprints are compatible.

Q: Are there differences in current rating between these parts?

A: The DIN-120RPC-DPS-TR specifies a 3A current rating. The 5650921-5 does not provide a current rating specification in available documentation. Verify current requirements against actual application demands before selection.

Q: What is the significance of the RoHS compliance difference?

A: The DIN-120RPC-DPS-TR is RoHS non-compliant, while the 5650921-5 is ROHS3 compliant. For new designs or systems subject to RoHS regulations, the substitute part is the appropriate choice. For legacy system maintenance, either part may be acceptable depending on regulatory context.

Q: Do both parts use the same insulation material?

A: Both employ glass-filled thermoplastic insulation with UL94 V-0 flammability rating. The DIN-120RPC-DPS-TR specifies polybutylene terephthalate (PBT) polyester, while the 5650921-5 specifies polymer thermoplastic. Both materials meet the same flammability standard and environmental requirements.

Q: Is the contact finish thickness specified for both parts?

A: The DIN-120RPC-DPS-TR specifies 3.00µin (0.076µm) gold plating thickness. The 5650921-5 does not provide contact finish thickness specification. Both parts use gold-plated contacts suitable for standard backplane applications.
