Engineering Selection Recommendations

Primary Recommendation: 171-009-113R021

This NorComp part maintains identical electrical and mechanical specifications to the 171-009-112-021 while offering higher inventory availability (1137 pieces). Both parts carry ROHS3 Compliant status and REACH Unaffected certification. The primary difference is packaging format (Tray vs. standard packaging). This selection eliminates cross-manufacturer qualification requirements.

Secondary Recommendations (Cross-Manufacturer):

HARTING parts (09661216703, 09661217703, 09651696712, 09670095654, 09670095655) provide higher current ratings (6.5A to 7.5A) and extended operating temperature ranges (-55°C to 125°C). All HARTING substitutes maintain ROHS3 Compliant status. Selection from this group requires verification of mechanical fit, as mounting type variations exist (Through Hole vs. Panel Mount).

Mercury United Electronics 627-009-220-042 offers ROHS3 Compliant status with nickel-plated steel shell and gold contact finish matching the original part. Current rating is reduced to 3A per contact, and operating temperature range is limited to -55°C to 85°C. This part is suitable for applications not requiring the full 5A rating of the original.

Hirose Electric SDEB-9P(55) and SDEG-9PF(55) provide panel mount capability with nickel-plated steel shell and gold contact finish. Both maintain ROHS3 Compliant status. SDEG-9PF(55) carries Last Time Buy status, indicating discontinued production. Current rating is 3A, suitable for signal-level applications only.

Compliance Status:

All recommended substitutes maintain ROHS3 Compliant and REACH Unaffected certifications. SDEG-9PF(55) carries RoHS Compliant status (non-ROHS3). All parts are classified under ECCN EAR99 and HTSUS 8536.69.4040.

Frequently Asked Questions (FAQ)

Q: Can 171-009-113R021 be used as a direct replacement for 171-009-112-021?

A: Yes. Both parts are manufactured by NorComp Inc. and share identical electrical and mechanical specifications. The primary difference is packaging format (Tray). No design changes are required.

Q: What is the key difference between NorComp and HARTING substitutes?

A: HARTING parts offer higher current ratings (6.5A to 7.5A vs. 5A) and extended operating temperature ranges (-55°C to 125°C vs. -50°C to 100°C). Mounting type may vary; verify Through Hole vs. Panel Mount compatibility with your PCB design.

Q: Are Hirose Electric parts suitable for all applications?

A: Hirose parts SDEB-9P(55) and SDEG-9PF(55) are rated for 3A current, limiting use to signal-level applications. SDEG-9PF(55) is Last Time Buy status, indicating production discontinuation. For new designs, SDEB-9P(55) is preferred if Hirose compatibility is required.

Q: What is the significance of "Panel Mount, Through Hole" vs. "Through Hole" mounting?

A: Panel Mount, Through Hole indicates the connector is designed for both panel-level mounting and PCB through-hole termination. Through Hole only indicates PCB termination capability. Verify your mechanical assembly requirements before substitution.

Q: Do all substitutes meet RoHS compliance?

A: All listed substitutes are ROHS3 Compliant except SDEG-9PF(55), which is RoHS Compliant (non-ROHS3). For applications requiring ROHS3 Compliant status, exclude SDEG-9PF(55).

Q: What packaging formats are available?

A: 171-009-113R021 is supplied in Tray format. HARTING parts are supplied in Bulk. Mercury United Electronics 627-009-220-042 and Hirose parts are supplied in Tray. Confirm packaging compatibility with your procurement and assembly processes.

Q: Can Mercury United 627-009-220-042 be used in high-current applications?

A: No. The 627-009-220-042 is rated for 3A per contact, compared to 5A for the original part. Use this substitute only in applications where current requirements do not exceed 3A per contact.

Q: Is contact finish (Gold vs. unspecified) a critical substitution factor?

A: Contact finish affects signal integrity and corrosion resistance. The original part specifies Gold finish with Flash thickness. HARTING parts 09661217703, 09670095654, and 09670095655 do not specify contact finish. Confirm contact material compatibility with your connector mating surfaces before substitution.
