Key Parameters

Substitute Part Grouping Explanation

The substitute part TE Connectivity AMP Connectors 5223963-1 is qualified as an equivalent based on the following critical parameters that determine functional interchangeability:

Matching Parameters:

• Connector category: Backplane Connectors
• Number of positions: 3 (Power)
• Number of rows: 1
• Mounting type: Board Edge, Through Hole, Right Angle
• Termination method: Press-Fit
• Contact finish: Gold (or Gold-Palladium)
• Operating temperature range: -55°C ~ 125°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

The primary distinction between the main part and substitute is the connector contact style: the 114402 uses male pins, while the 5223963-1 uses male blades. Both configurations serve power distribution applications in backplane connector applications and maintain electrical and mechanical compatibility within the specified parameter set.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity AMP Connectors 5223963-1 is the designated substitute for the obsolete TE Connectivity Erni 114402. Selection of this substitute is supported by the following engineering criteria:

Product Status Alignment: The 5223963-1 maintains active product status, ensuring ongoing availability and manufacturing support, whereas the 114402 is obsolete and subject to supply discontinuation.

Compliance Certification: Both connectors maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity ratings, ensuring regulatory and environmental compatibility in existing applications.

Electrical and Mechanical Specifications: The substitute part maintains identical operating temperature range (-55°C ~ 125°C), identical mounting configuration (board edge, through-hole, right-angle), and identical termination method (press-fit). The substitute provides an additional voltage rating specification of 250V, which represents enhanced electrical capability.

Contact Finish Specification: The substitute offers gold or gold-palladium contact finish options, providing equivalent or superior corrosion resistance compared to the main part's gold finish.

The primary design consideration for implementation is the transition from male pin contacts to male blade contacts. This change requires verification of mating connector compatibility at the system level, as the blade contact geometry differs from pin geometry.

Frequently Asked Questions (FAQ)

Q: What is the primary reason the TE Connectivity Erni 114402 requires a substitute?

A: The 114402 is classified as obsolete, indicating discontinued manufacturing and limited remaining inventory. The TE Connectivity AMP Connectors 5223963-1 is an active product that provides equivalent functionality for ongoing procurement and system support.

Q: Are the 114402 and 5223963-1 directly interchangeable?

A: Both connectors share identical mounting type (board edge, through-hole, right-angle), termination method (press-fit), number of positions (3), operating temperature range (-55°C ~ 125°C), and compliance certifications (ROHS3, MSL 1). The primary difference is contact style: the 114402 uses male pins while the 5223963-1 uses male blades. Interchangeability depends on mating connector compatibility with blade versus pin contact geometry.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by: connector category (backplane connectors), number of positions (3), mounting type (board edge, through-hole, right-angle), termination method (press-fit), operating temperature range (-55°C ~ 125°C), and compliance status (ROHS3, MSL 1). These parameters ensure functional equivalence in power distribution applications.

Q: Does the 5223963-1 provide additional electrical specifications?

A: Yes. The 5223963-1 specifies a 250V voltage rating, whereas the 114402 does not provide a voltage rating specification. This represents enhanced electrical capability in the substitute part.

Q: What packaging format is available for the substitute part?

A: The TE Connectivity AMP Connectors 5223963-1 is supplied in tube packaging, with 3020 pieces available in current inventory.

Q: Are both parts RoHS compliant?

A: Yes. Both the TE Connectivity Erni 114402 and TE Connectivity AMP Connectors 5223963-1 are ROHS3 compliant, meeting regulatory requirements for hazardous substance restrictions.

Q: What is the moisture sensitivity level for both connectors?

A: Both connectors are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions and no special storage or handling requirements.
