Engineering Selection Recommendations
The TE Connectivity AMP Connectors 5223964-1 is the designated substitute for the obsolete TE Connectivity Erni 114403. Both connectors maintain identical operating temperature specifications (-55°C ~ 125°C) and equivalent environmental compliance certifications (ROHS3, MSL 1, EAR99).
The substitute part is currently in active production status with confirmed inventory availability (2332 pcs), whereas the original part is obsolete. Both connectors employ press-fit termination with gold-plated contacts and are configured for board edge, through-hole, right-angle mounting in single-row, 3-position power applications.
The 5223964-1 operates within the UPM (Universal Power Modules) series and includes board guide features. Contact finish specifications for the substitute part include gold or gold-palladium plating, which exceeds the original gold-only specification. Voltage rating for the substitute is specified at 250V.
Selection of the 5223964-1 is appropriate for applications requiring direct replacement of the 114403 in backplane connector applications.
Frequently Asked Questions (FAQ)
Q: What is the primary reason for substituting the 114403?
A: The 114403 is classified as an obsolete product. The 5223964-1 substitute is an active production part with current inventory availability, ensuring long-term supply continuity for legacy system support.
Q: Are the mounting configurations identical between the two parts?
A: Yes. Both the 114403 and 5223964-1 are configured for board edge, through-hole, right-angle mounting with single-row, 3-position layouts and press-fit termination.
Q: Do the operating temperature ranges match?
A: Yes. Both connectors operate across the identical temperature range of -55°C ~ 125°C.
Q: What is the difference between male pins and male blades?
A: The 114403 features male pin contacts, while the 5223964-1 features male blade contacts. Both are male contact elements suitable for mating with corresponding female receptacles in backplane applications.
Q: Are both parts RoHS3 compliant?
A: Yes. Both the 114403 and 5223964-1 are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity ratings.
Q: What is the contact finish specification for the substitute part?
A: The 5223964-1 specifies gold or gold-palladium contact finish, which is compatible with and exceeds the original 114403 gold-only specification.
Q: Is the pitch specification provided for the substitute part?
A: The pitch specification is not provided in the substitute part documentation. The 114403 specifies 0.079" (2.00mm) pitch. Mechanical compatibility should be verified during integration.
Q: What packaging format is available for the substitute part?
A: The 5223964-1 is supplied in tube packaging.
