Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1703221 is determined by the following critical parameters:

• Series Compatibility: Both parts must belong to the COMBICON DFK-IPCV series
• Electrical Ratings: Voltage (600 V UL) and current (5 A UL) ratings must be identical
• Mechanical Configuration: 3 positions per level with 0.400" (10.16mm) pitch
• Connection Type: Female socket header with PCB pin straight rear connection
• Panel Mounting: Snap lock mechanism with compatible panel thickness range (0.039 ~ 0.118")
• Compliance: RoHS compliance and MSL rating of 1 (unlimited)
• Color: Green housing

The Phoenix Contact 1703069 meets all substitution criteria as an active product within the same series, maintaining identical electrical ratings, mechanical pitch, position count, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1703069 serves as the direct substitute for the obsolete 1703221 model. Both components maintain identical electrical specifications (600 V UL, 5 A UL), mechanical pitch (0.400"), position configuration (3 positions), and compliance certifications (RoHS compliant, MSL 1). The 1703069 is currently in active production status, ensuring long-term availability and supply chain continuity.

The primary dimensional difference is the width measurement: the 1703221 measures 2.817" (71.56mm) while the 1703069 measures 2.150" (54.60mm). This reduction in width may require panel layout verification during integration. The panel mount type differs slightly, with the 1703221 featuring a front flange configuration compared to the standard snap lock of the 1703069. Both maintain compatibility with the specified panel thickness range of 0.039 ~ 0.118" (1.0 ~ 3.0mm).

Frequently Asked Questions (FAQ)

Q: Can the 1703069 be used as a direct replacement for the 1703221?

A: The 1703069 is electrically and mechanically compatible as a substitute. All critical parameters including voltage rating, current rating, pitch, position count, and compliance certifications are identical. Physical layout verification is required due to the width difference (2.817" vs 2.150").

Q: What is the significance of the width difference between these parts?

A: The 1703069 has a reduced width of 2.150" (54.60mm) compared to the 1703221 at 2.817" (71.56mm). This dimensional change may affect panel cutout dimensions and mounting hole spacing. Panel layout must be evaluated before implementation.

Q: Are both parts RoHS compliant?

A: Yes, both the 1703221 and 1703069 are RoHS compliant with an MSL rating of 1 (unlimited moisture sensitivity level).

Q: What is the difference between the panel mount types?

A: The 1703221 features a 2-piece snap lock with front flange, while the 1703069 uses a standard 2-piece snap lock configuration. Both accommodate the same panel thickness range and maintain snap lock functionality.

Q: Why is the 1703221 listed as obsolete?

A: The 1703221 has been discontinued by Phoenix Contact. The 1703069 represents the active product line continuation within the COMBICON DFK-IPCV series.

Q: Are there any packaging differences?

A: The 1703221 packaging information is not specified in available data. The 1703069 is supplied in bulk packaging.
