Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1-2178711-2 connector is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Connector type (Receptacle)
• Number of positions (12)
• Pitch - mating (0.100" / 2.54mm)
• Number of rows (2)
• Row spacing - mating (0.100" / 2.54mm)
• Voltage rating (100VDC)
• Contact type (Forked)

Mechanical Compatibility Parameters:

• Mounting type (Surface Mount)
• Termination method (Solder)
• Fastening type (Push-Pull)
• Insulation material (Polyamide PA46, Nylon 4/6, Glass Filled)
• Insulation height (0.209" / 5.30mm)
• Series designation (Micro-MaTch)

Identified Substitutes: The following TE Connectivity AMP Connectors parts satisfy all critical electrical and mechanical parameters and are classified as active products:

1. 1-188275-2 - Active status, expanded operating temperature range
2. 8-188275-2 - Active status, expanded operating temperature range, Pick and Place feature

Both substitute parts maintain full compatibility with the original 1-2178711-2 connector across all specified electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes:

Both 1-188275-2 and 8-188275-2 are direct functional equivalents to the obsolete 1-2178711-2 connector. Selection between these two active alternatives is based on the following criteria:

1-188275-2 Selection Criteria:

• Active product status with established supply chain
• RoHS compliant certification
• Expanded operating temperature range (-40°C to 105°C) provides enhanced thermal margin over the original part (-30°C to 85°C)
• Phosphor bronze contact material offers improved durability compared to brass
• Suitable for general purpose and automotive applications

8-188275-2 Selection Criteria:

• Active product status with highest available inventory (6769 pcs)
• ROHS3 compliant certification
• Expanded operating temperature range (-40°C to 105°C)
• Phosphor bronze contact material
• Pick and Place feature designation indicates optimized manufacturing compatibility
• Suitable for general purpose and automotive applications
• REACH Unaffected status provides regulatory clarity

Compliance Considerations: Both substitute parts maintain the same electrical rating (100VDC), mechanical configuration (12-position, 2-row, 0.100" pitch), and insulation material specifications as the original part. The substitutes provide enhanced compliance certifications (ROHS3 and REACH status) and extended operating temperature ranges, making them suitable for applications requiring broader environmental performance.

Frequently Asked Questions (FAQ)

Q: Can 1-188275-2 or 8-188275-2 directly replace 1-2178711-2 in existing designs?

A: Yes. Both substitute parts maintain identical electrical and mechanical specifications across all critical parameters: 12-position receptacle configuration, 0.100" (2.54mm) pitch, 2-row layout, surface mount solder termination, push-pull fastening, and 100VDC voltage rating. The connectors are mechanically and electrically interchangeable.

Q: What are the differences between the substitute parts?

A: The primary differences are inventory availability and manufacturing features. Part 8-188275-2 has higher inventory (6769 pcs vs. 3987 pcs for 1-188275-2) and includes a Pick and Place feature designation. Both parts are active products with identical electrical and mechanical specifications.

Q: Why do the substitute parts have different insulation colors (red vs. black)?

A: Insulation color is a cosmetic identifier and does not affect electrical or mechanical compatibility. The color change reflects manufacturing updates in the active product line. Functional performance remains identical.

Q: What is the significance of the contact material change from brass to phosphor bronze?

A: Phosphor bronze provides improved mechanical durability and contact reliability compared to brass. This material upgrade in the active substitute parts enhances long-term performance without affecting electrical compatibility or voltage rating.

Q: Are the substitute parts suitable for automotive applications?

A: Yes. Both 1-188275-2 and 8-188275-2 are rated for automotive applications. The expanded operating temperature range (-40°C to 105°C) and UL94 V-0 flammability rating support automotive environmental requirements.

Q: What is the difference between RoHS and ROHS3 compliance?

A: Both certifications indicate compliance with Restriction of Hazardous Substances regulations. ROHS3 represents the current regulatory standard. Part 8-188275-2 carries ROHS3 certification, while 1-188275-2 carries RoHS certification. Both are compliant with current regulatory requirements.

Q: Does the expanded operating temperature range of the substitutes affect compatibility?

A: No. The expanded range (-40°C to 105°C for substitutes vs. -30°C to 85°C for the original) provides additional thermal margin and does not reduce compatibility. Applications operating within the original temperature range remain fully compatible.

Q: Are there any packaging differences between the main part and substitutes?

A: No. All three parts are supplied in Cut Tape (CT) packaging with identical moisture sensitivity level (MSL 1 - Unlimited), ensuring consistent handling and storage requirements.

Q: Which substitute part should be selected for new designs?

A: For new designs, 8-188275-2 is recommended based on active product status, ROHS3 compliance, REACH Unaffected status, highest inventory availability, and Pick and Place feature designation. This part provides the most current regulatory alignment and manufacturing optimization.
