TE Connectivity 1-120527-1 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 1-120527-1 is a 64-position rectangular connector plug designed for surface mount applications with center strip contacts and gold plating. This connector operates within the Free Height (FH) IEEE 1386 and PMC series standards. The part is currently Active in product status and maintains RoHS compliance with Moisture Sensitivity Level 1 (unlimited shelf life). Substitute parts are identified when inventory constraints, specific compliance requirements, or contact finish specifications necessitate alternative sourcing while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the 1-120527-1 is determined by strict equivalence across the following critical parameters: connector type (Plug, Center Strip Contacts), number of positions (64), pitch (0.039"/1.00mm), number of rows (2), mounting type (Surface Mount), height above board (0.329"/8.35mm), mated stacking heights (10mm, 12mm, 13mm, 15mm), and board guide feature. Parts meeting these criteria are classified as substitutes regardless of variations in contact finish material, contact finish thickness, RoHS revision level, or REACH classification status. The substitute parts identified for 1-120527-1 are 1-5120527-1 and 1-5146888-1, both of which maintain full mechanical and electrical compatibility through identical pitch, position count, mounting configuration, and physical dimensions.

Parameter Comparison

Engineering Selection Recommendations

All three parts—1-120527-1, 1-5120527-1, and 1-5146888-1—are Active products from TE Connectivity AMP Connectors and maintain full mechanical and electrical interchangeability. Selection between these parts is determined by specific application requirements and compliance mandates.

The 1-120527-1 (main part) and 1-5146888-1 (substitute) both feature gold contact finish at 50.0µin (1.27µm) thickness and are suitable for applications requiring enhanced corrosion resistance and contact reliability. The 1-120527-1 carries RoHS Compliant status and is REACH Affected, while 1-5146888-1 carries ROHS3 Compliant status and is REACH Unaffected.

The 1-5120527-1 (substitute) features galvanized contact finish at 30.0µin (0.76µm) thickness and carries ROHS3 Compliant status. This part is appropriate for cost-sensitive applications where the reduced contact finish thickness and galvanized plating meet performance specifications.

All parts maintain identical electrical characteristics, pitch, position count, mounting configuration, and physical dimensions. Selection should be based on contact finish requirements, compliance certifications applicable to the end application, and inventory availability.

Frequently Asked Questions (FAQ)

Q: Are 1-5120527-1 and 1-5146888-1 direct replacements for 1-120527-1?

A: Both parts are mechanically and electrically compatible substitutes. The 1-5120527-1 differs in contact finish material (galvanized versus gold) and finish thickness (30.0µin versus 50.0µin). The 1-5146888-1 maintains identical contact finish specifications (gold, 50.0µin) but differs in RoHS revision level and REACH classification.

Q: What is the significance of the contact finish difference between these parts?

A: Contact finish affects corrosion resistance, contact resistance stability, and long-term reliability. Gold plating (1-120527-1 and 1-5146888-1) provides superior corrosion resistance and contact reliability compared to galvanized finish (1-5120527-1). The contact finish thickness specification (50.0µin for gold, 30.0µin for galvanized) reflects the plating process standards for each material.

Q: Do all three parts have the same physical dimensions and mounting footprint?

A: Yes. All three parts share identical pitch (0.039"/1.00mm), position count (64), number of rows (2), height above board (0.329"/8.35mm), and mated stacking heights (10mm, 12mm, 13mm, 15mm). They are pin-compatible and footprint-compatible on PCBs designed for any of these part numbers.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant status?

A: RoHS Compliant indicates compliance with the original Restriction of Hazardous Substances directive. ROHS3 Compliant indicates compliance with the revised RoHS 3 directive (2011/65/EU as amended). Both designations confirm restriction of hazardous substances; ROHS3 represents the current regulatory standard.

Q: How does REACH Affected versus REACH Unaffected status impact part selection?

A: REACH Affected status (1-120527-1) indicates the part contains substances subject to REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) regulations. REACH Unaffected status (1-5146888-1) indicates the part does not contain such substances. Selection depends on end-use application regulatory requirements and supply chain compliance mandates.

Q: Are all three parts available in Tape & Reel packaging?

A: Yes. All three parts are supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes.

Q: What is Moisture Sensitivity Level 1, and how does it affect handling?

A: Moisture Sensitivity Level 1 (Unlimited) indicates the component has unlimited shelf life and does not require special moisture-controlled storage or handling procedures. All three parts carry this classification.
