Key Parameters

Substitute Part Grouping Explanation

Substitution for the EX80-54S is determined by strict equivalence across the following critical parameters:

• Connector Type & Configuration: Receptacle with center strip contacts
• Contact Count & Arrangement: 54 positions in 2-row configuration
• Pitch Specification: 0.024" (0.60mm) contact spacing
• Mounting Technology: Surface mount with board guide feature
• Electrical Interface: Gold contact finish for reliable signal transmission
• Physical Envelope: Height above board of 0.142" (3.60mm)
• Environmental Classification: MSL 1 rating

The identified substitute part EX80-54S(30) maintains full equivalence across all specified electrical and mechanical parameters, differing only in packaging configuration (Cut Tape versus standard packaging).

Parameter Comparison

Engineering Selection Recommendations

Both the EX80-54S and EX80-54S(30) are classified as obsolete products. The EX80-54S(30) variant provides the additional advantage of RoHS compliance certification, which may be required for applications subject to environmental regulations or customer specifications. The packaging difference (Cut Tape for the EX80-54S(30)) does not affect electrical or mechanical compatibility. Selection between these parts should be based on regulatory requirements, inventory availability, and packaging handling capabilities within the assembly process.

Frequently Asked Questions (FAQ)

Q: Are EX80-54S and EX80-54S(30) electrically and mechanically interchangeable?

A: Yes. Both parts maintain identical specifications for connector type, position count, pitch, mounting method, contact finish, and physical dimensions. They are direct functional equivalents.

Q: What is the difference between EX80-54S and EX80-54S(30)?

A: The primary difference is packaging format. EX80-54S(30) is supplied in Cut Tape (CT) packaging, while EX80-54S uses standard packaging. Additionally, EX80-54S(30) carries RoHS compliance certification.

Q: Why is RoHS compliance important for the EX80-54S(30)?

A: RoHS compliance indicates the part meets restrictions on hazardous substances. This certification is mandatory for many applications, particularly in consumer electronics and regulated industries. If your application requires RoHS compliance, EX80-54S(30) is the appropriate selection.

Q: Can I use EX80-54S(30) in place of EX80-54S in existing designs?

A: Yes, provided your assembly process can accommodate Cut Tape packaging. The electrical and mechanical specifications are identical, ensuring drop-in compatibility at the component level.

Q: What does MSL 1 (Unlimited) mean for these connectors?

A: MSL 1 indicates the lowest moisture sensitivity level, meaning these components have unlimited shelf life and do not require special moisture control during storage or handling.
