CES-102-01-S-S Equivalent & Substitute Parts

Part Overview

The CES-102-01-S-S is a 2-position receptacle connector manufactured by Samtec Inc., designed for board-to-board applications with 0.100" (2.54mm) pitch spacing. This through-hole component features gold-plated mating contacts and tin-plated posts, with solder termination and push-pull fastening. The connector is currently active in production with 785 units in stock.

Substitute parts are identified when equivalent electrical and mechanical parameters align with the main part specifications, enabling direct replacement in applications where the core functional requirements remain unchanged.

Key Parameters

Substitute Part Grouping Explanation

The 929870-01-02-RB manufactured by 3M qualifies as a substitute based on the following alignment of critical parameters:

• Connector type: Both are receptacles with 2 positions
• Mating pitch: Both use 0.100" (2.54mm) spacing
• Mounting and termination: Both are through-hole solder-terminated
• Fastening mechanism: Both employ push-pull fastening
• Contact finish: Both feature gold-plated mating surfaces with tin-plated posts
• Insulation material: Both use polybutylene terephthalate (PBT)
• Flammability rating: Both meet UL94 V-0 standard
• Board-to-board application: Both are designed for this style

Substitution is valid where these core parameters determine functional compatibility in the application circuit.

Parameter Comparison

Engineering Selection Recommendations

Both the CES-102-01-S-S and 929870-01-02-RB are active production components with equivalent regulatory compliance. The CES-102-01-S-S offers an extended operating temperature range of -55°C to 125°C compared to the 929870-01-02-RB range of -40°C to 105°C. The 929870-01-02-RB provides specified electrical ratings of 1A current and 1000V voltage, whereas the CES-102-01-S-S does not list these parameters.

Physical differences include insulation height (0.200" versus 0.150") and contact post length (0.128" versus 0.125"). The CES-102-01-S-S uses phosphor bronze contacts while the 929870-01-02-RB uses copper alloy. The 929870-01-02-RB insulation material is glass-filled PBT, providing enhanced mechanical properties compared to standard PBT.

Selection between these parts depends on application-specific requirements for operating temperature range, electrical load specifications, and mechanical clearance constraints.

Frequently Asked Questions (FAQ)

Q: What determines if the 929870-01-02-RB can replace the CES-102-01-S-S?

A: Substitution is valid when the application requirements align with the common parameters: 2-position receptacle configuration, 0.100" pitch spacing, through-hole solder termination, push-pull fastening, and gold-plated mating contacts. Differences in insulation height, contact post length, and operating temperature range must be evaluated against specific application constraints.

Q: Are there differences in contact geometry between these parts?

A: Yes. The CES-102-01-S-S features female socket contacts, while the 929870-01-02-RB uses forked contacts. Both are square-shaped and compatible with standard 0.100" pitch mating components. Contact material differs: phosphor bronze versus copper alloy.

Q: What is the significance of the insulation height difference?

A: The CES-102-01-S-S has an insulation height of 0.200" (5.08mm) compared to 0.150" (3.81mm) for the 929870-01-02-RB. This affects board-level clearance and stacking height in multi-connector applications. Verify PCB layout compatibility before substitution.

Q: How do the operating temperature ranges compare?

A: The CES-102-01-S-S operates from -55°C to 125°C, providing a wider temperature envelope than the 929870-01-02-RB (-40°C to 105°C). Applications requiring extended low-temperature operation should retain the CES-102-01-S-S.

Q: What are the electrical rating differences?

A: The 929870-01-02-RB specifies 1A current rating and 1000V voltage rating. The CES-102-01-S-S does not provide these electrical specifications. Applications with defined electrical load requirements should reference the 929870-01-02-RB ratings or contact the manufacturer for CES-102-01-S-S electrical limits.

Q: Are both parts RoHS compliant?

A: Yes. The CES-102-01-S-S is ROHS3 compliant and the 929870-01-02-RB is RoHS compliant. Both are REACH unaffected. Both meet regulatory requirements for restricted substance compliance.
