TE Connectivity AMP Connectors 171827-1 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 171827-1 is a 17-position rectangular connector receptacle housing from the MIC (Multi-Interlock) series. This component is classified as a Last Time Buy product, indicating discontinued production with limited remaining inventory. The connector features a natural polyamide (PA66, Nylon 6/6) housing with crimp-style tab contacts, designed for free-hanging in-line mounting applications. Substitute parts are necessary due to the Last Time Buy status and to ensure continued availability for new production runs and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 171827-1 are identified based on strict parametric equivalence within the MIC series rectangular connectors category. The substitution logic is based on the following critical parameters that must remain constant:

• Connector type (Receptacle)
• Number of positions (17)
• Number of rows (2)
• Row spacing (0.236" / 6.00mm)
• Contact type (Tab)
• Contact termination method (Crimp)
• Mounting configuration (Free Hanging In-Line)
• Insulation material composition (Polyamide/Nylon)
• Operating temperature range (-30°C ~ 105°C)
• RoHS compliance status
• MSL rating (1 - Unlimited)

Variations in housing color (natural versus green) do not affect electrical or mechanical compatibility, as color is a cosmetic parameter that does not impact connector function or interchangeability. All substitute parts maintain identical electrical and mechanical specifications required for direct replacement.

Parameter Comparison

Engineering Selection Recommendations

171827-4 is the primary substitute for 171827-1. Both parts share identical specifications across all critical electrical and mechanical parameters within the MIC series. The 171827-4 maintains RoHS compliance and MSL rating 1 status. The part is currently in Active product status with higher inventory availability (1067 pieces) compared to the Last Time Buy 171827-1. The only difference is housing color (green versus natural), which does not affect functional compatibility or performance.

172509-4 is an alternative substitute that maintains parametric equivalence for all critical connector specifications. This part is also in Active product status with substantial inventory (892 pieces). The insulation material specification lists "Polyamide (PA), Nylon" without the specific PA66 designation, and operating temperature range is explicitly stated as -30°C ~ 105°C, matching the main part. RoHS compliance and MSL rating 1 are maintained. This part is suitable for applications where the main part is no longer available.

Both substitute parts are RoHS compliant and carry MSL rating 1 (Unlimited), ensuring compliance with environmental and moisture sensitivity requirements. Selection between 171827-4 and 172509-4 should be based on inventory availability, lead time requirements, and any design-specific color preferences.

Frequently Asked Questions (FAQ)

Q: Can 171827-4 be used as a direct replacement for 171827-1?

A: Yes. The 171827-4 maintains identical electrical and mechanical specifications including connector type, position count, row configuration, row spacing, contact type, termination method, mounting style, insulation material, operating temperature range, RoHS compliance, and MSL rating. The housing color difference (green versus natural) does not affect functional compatibility.

Q: What is the difference between 171827-4 and 172509-4?

A: Both parts are parametrically equivalent for all critical connector specifications. The primary differences are the base product number (171827 versus 172509) and the insulation material specification detail (PA66 Nylon 6/6 versus PA Nylon). Both maintain the required operating temperature range of -30°C ~ 105°C, RoHS compliance, and MSL rating 1.

Q: Why is the 171827-1 marked as Last Time Buy?

A: Last Time Buy status indicates that the manufacturer has discontinued production of this part number. Existing inventory is limited, and no future production is planned. Substitute parts in Active status should be selected for new designs and ongoing production requirements.

Q: Are the substitute parts compatible with existing connector systems designed for 171827-1?

A: Yes. Both 171827-4 and 172509-4 are mechanically and electrically compatible with systems designed for 171827-1. The 17-position, 2-row configuration with 0.236" row spacing, tab contact type, and crimp termination remain identical across all three part numbers.

Q: Does housing color affect electrical performance?

A: No. Housing color is a cosmetic parameter that does not impact electrical performance, signal integrity, or mechanical function. The natural and green housing options are functionally equivalent.

Q: What is MSL rating 1 and why is it important?

A: MSL (Moisture Sensitivity Level) rating 1 indicates Unlimited shelf life with no moisture sensitivity restrictions. This means the connector can be stored and handled without special moisture control measures, simplifying inventory management and reducing handling costs.

Q: Are all three parts RoHS compliant?

A: Yes. The main part 171827-1 and both substitute parts 171827-4 and 172509-4 are RoHS compliant, meeting environmental and hazardous substance restrictions for electronic components.
