TE Connectivity 2355827-1 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 2355827-1 is a 320-position connector array with female sockets designed for surface mount applications in aerospace, defense, and marine environments. This component is part of the Mezalok XMC series and features gold-plated contacts with a 1.27mm center-line pitch. The part maintains Active product status and is currently in stock with 948 units available.

Substitute parts are identified to provide alternative packaging and sourcing options while maintaining identical electrical and mechanical specifications. This is necessary to accommodate different manufacturing workflows, inventory management strategies, and supply chain requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2355827-1 is based on strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications in the following areas:

Electrical Parameters:

• 320-position connector array configuration
• 0.050" (1.27mm) center-line pitch
• 8-row arrangement
• Female socket connector type
• Gold contact finish at 50.0µin (1.27µm) thickness

Mechanical Parameters:

• Surface mount mounting type
• 0.236" (6.00mm) height above board
• 10mm mated stacking height
• Pick and place feature compatibility

Environmental & Compliance Parameters:

• Moisture Sensitivity Level 1 (Unlimited)
• Active product status
• TE Connectivity Aerospace, Defense and Marine manufacturer

The primary distinction between the main part and its substitute is packaging format. The 2355827-1 is supplied in Tape & Reel (TR) format, while the substitute 2355827-2 is supplied in Cut Tape (CT) format. Both formats contain identical components with no functional or performance differences.

Parameter Comparison

Engineering Selection Recommendations

Both the 2355827-1 and 2355827-2 are Active products manufactured by TE Connectivity Aerospace, Defense and Marine and are suitable for direct substitution based on electrical and mechanical equivalence.

Selection Criteria:

The 2355827-1 (Tape & Reel packaging) is appropriate for high-volume automated assembly operations where continuous reel feeding into pick-and-place equipment is standard practice.

The 2355827-2 (Cut Tape packaging) is appropriate for lower-volume production runs, manual assembly operations, or applications where individual component handling is required.

The 2355827-2 provides documented ROHS3 compliance certification, which may be required for specific regulatory or customer specifications. The 2355827-1 does not specify RoHS status in the provided documentation.

Both parts maintain identical MSL 1 (Unlimited) moisture sensitivity ratings, eliminating moisture management as a differentiation factor.

Both parts are currently in stock with comparable inventory levels (948 units for 2355827-1 and 940 units for 2355827-2), supporting immediate availability for either selection.

Frequently Asked Questions (FAQ)

Q: Can the 2355827-2 (Cut Tape) be used as a direct replacement for the 2355827-1 (Tape & Reel)?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format. The component itself, including all electrical characteristics, mechanical dimensions, and contact specifications, is identical between the two part numbers.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) packaging?

A: Tape & Reel packaging supplies components on a continuous reel suitable for automated pick-and-place equipment. Cut Tape packaging supplies components on individual tape segments, typically used for manual assembly, lower-volume production, or component kitting. The actual component is identical in both formats.

Q: Are there any performance differences between 2355827-1 and 2355827-2?

A: No. Both parts have identical electrical performance, mechanical specifications, contact finish, pitch, position count, and all other functional parameters. Performance is equivalent.

Q: Does the 2355827-1 meet RoHS3 compliance?

A: The 2355827-1 documentation does not specify RoHS status. The 2355827-2 is documented as ROHS3 Compliant. If RoHS3 compliance is a requirement, the 2355827-2 is the documented choice.

Q: What is the MSL rating for both parts?

A: Both the 2355827-1 and 2355827-2 have an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Can these parts be used interchangeably in the same PCB assembly?

A: Yes. The 2355827-1 and 2355827-2 are mechanically and electrically interchangeable. PCB footprints, mating heights, and all dimensional specifications are identical.

Q: Which part should be selected for high-volume manufacturing?

A: The 2355827-1 (Tape & Reel) is optimized for high-volume automated assembly due to continuous reel compatibility with standard pick-and-place equipment.

Q: Which part should be selected for low-volume or prototype applications?

A: The 2355827-2 (Cut Tape) is suitable for low-volume production, prototyping, or manual assembly workflows where individual component handling is standard practice.

Q: Are both parts currently available?

A: Yes. The 2355827-1 has 948 units in stock, and the 2355827-2 has 940 units in stock.
