Substitute Part Grouping Explanation
Substitution eligibility for the Phoenix Contact 1703247 is determined by the following critical parameters:
- Electrical Specifications: Voltage rating (600 V UL) and current rating (5 A UL) must be maintained or exceeded
- Mechanical Configuration: 5 positions per level with 0.400" (10.16mm) pitch spacing
- Connection Type: Female socket front panel connection with straight PCB pin rear connection
- Panel Mounting: Snap lock mechanism with compatible panel thickness range (0.039 ~ 0.118")
- Series Compatibility: COMBICON DFK-IPCV series designation
- Environmental Compliance: RoHS compliance and MSL rating
The Phoenix Contact 1703085 qualifies as a direct substitute based on matching all critical electrical and mechanical parameters within the allowed specification range.

Engineering Selection Recommendations
The Phoenix Contact 1703085 is the qualified substitute for the obsolete 1703247 terminal block header. Both components maintain identical electrical ratings (600 V UL, 5 A UL), mechanical configuration (5 positions, 0.400" pitch), and environmental compliance (RoHS compliant, MSL 1). The 1703085 is currently in active product status with confirmed inventory availability, whereas the 1703247 is obsolete.
The primary dimensional difference is the width specification: the 1703247 measures 3.617" (91.88mm) while the 1703085 measures 2.950" (74.92mm). This dimensional variance must be evaluated within the context of the specific application's panel mounting requirements and available space constraints.
Both components employ identical snap lock panel mounting mechanisms compatible with panel thickness ranges of 0.039 ~ 0.118" (1.0 ~ 3.0mm). The substitute maintains full compliance with RoHS regulations and identical moisture sensitivity classification.
Frequently Asked Questions (FAQ)
Q: Can the 1703085 directly replace the 1703247 in existing applications?
A: The 1703085 matches all critical electrical and mechanical parameters including voltage rating, current rating, position count, pitch spacing, and connection types. The primary consideration is the width difference (3.617" versus 2.950"). Panel mounting compatibility depends on available space and mounting hole alignment in the specific application.
Q: What are the key parameters that determine substitution eligibility?
A: Substitution is based on matching electrical specifications (600 V UL, 5 A UL), mechanical configuration (5 positions, 0.400" pitch), connection type (female socket front, straight PCB pins rear), panel mounting mechanism (snap lock), and environmental compliance (RoHS, MSL 1). All these parameters are identical between the two components.
Q: Why is the 1703247 classified as obsolete?
A: The 1703247 is listed as obsolete in the current product portfolio. The 1703085 represents the active equivalent within the COMBICON DFK-IPCV series and is recommended for new designs and ongoing system support.
Q: Are there packaging differences between these components?
A: The 1703247 packaging specification is not provided. The 1703085 is supplied in bulk packaging. Packaging format should be confirmed based on procurement requirements.
Q: What is the panel thickness compatibility range?
A: Both the 1703247 and 1703085 support panel thickness ranges of 0.039 ~ 0.118" (1.0 ~ 3.0mm) with the snap lock mounting mechanism.
