Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 51751-1 is determined by alignment across the following critical parameters:

Connector Classification: Both the main part and substitute must function as SMC Coaxial Connectors (RF) within the same connector category.

Connector Style & Type: The substitute must maintain SMC connector style with Jack, Male Pin configuration to ensure mechanical and electrical compatibility.

Impedance Rating: The 50 Ohms impedance specification is mandatory for RF signal integrity and system compatibility.

Mounting Configuration: Bulkhead mounting with panel mount capability and threaded fastening type ensures physical installation compatibility.

Electrical & Environmental Compliance: RoHS compliance status, ECCN classification (EAR99), and HTSUS code (8536.69.4010) must align for regulatory and procurement purposes.

Moisture Sensitivity: MSL 1 (Unlimited) classification ensures no moisture-related handling restrictions during storage and assembly.

The substitute part 131-6303-401 from Cinch Connectivity Solutions Johnson satisfies all these critical parameters and is classified as Active, providing long-term availability assurance.

Parameter Comparison

Engineering Selection Recommendations

For Obsolete Part Replacement: The TE Connectivity 51751-1 is designated Obsolete. The Cinch Connectivity Solutions Johnson 131-6303-401 is classified as Active and provides continuity for applications requiring SMC Bulkhead Jack Assembly functionality.

Compliance Alignment: Both parts share identical ECCN (EAR99) and HTSUS (8536.69.4010) classifications, ensuring regulatory consistency. The substitute part carries explicit RoHS Compliance certification, whereas the main part requires inventory verification for RoHS status.

Moisture Handling: Both parts maintain MSL 1 (Unlimited) classification, eliminating moisture sensitivity constraints during procurement, storage, and assembly operations.

Availability & Supply Chain: The substitute part maintains Active product status with 1090 pieces in new original stock, compared to the Obsolete status of the main part with 814 pieces available. Active status provides assurance of continued availability for future procurement cycles.

Frequently Asked Questions (FAQ)

Q: Can the Cinch 131-6303-401 directly replace the TE Connectivity 51751-1 in existing applications?

A: The Cinch 131-6303-401 functions as an equivalent substitute based on shared connector category (Coaxial Connectors RF), connector style (SMC), mounting configuration (Bulkhead Panel Mount), impedance rating (50 Ohms), and regulatory classifications (ECCN EAR99, HTSUS 8536.69.4010). Both parts maintain identical MSL 1 (Unlimited) moisture sensitivity levels. Mechanical and electrical compatibility is established through these aligned parameters.

Q: What is the significance of the Active product status for the substitute part?

A: Active product status indicates the Cinch 131-6303-401 remains in current production and distribution. This contrasts with the Obsolete status of the TE Connectivity 51751-1, which is no longer manufactured. Active status provides assurance of continued availability for procurement, replacement, and future system maintenance without supply chain discontinuation risk.

Q: Are there packaging differences between the main part and substitute?

A: The TE Connectivity 51751-1 packaging is not specified in the provided data. The Cinch 131-6303-401 is supplied in Bulk packaging and includes 4 pieces per connector assembly: 1 Connector, 1 Lockwasher, 1 Nut, and 1 Sleeve. Verify packaging requirements against your procurement specifications.

Q: How do the RoHS compliance statuses compare?

A: The TE Connectivity 51751-1 requires inventory verification for RoHS status. The Cinch 131-6303-401 carries explicit RoHS Compliant certification. For applications with mandatory RoHS compliance requirements, the substitute part provides documented compliance assurance.

Q: What cable groups are compatible with the substitute connector?

A: The Cinch 131-6303-401 accommodates cable groups RG-161, 174, 179A, 179B, 187, 187A, 188, 188A, and 316. Verify cable compatibility against your system specifications and existing cable inventory.

Q: Are there operational temperature or frequency limitations for the substitute part?

A: The Cinch 131-6303-401 operates across the temperature range -65°C to 165°C with maximum frequency rating of 10 GHz. Verify these specifications align with your application requirements.
