84115503 DC Input Module 4-32V Equivalent & Substitute Parts

Part Overview

The 84115503 is a DC input module manufactured by Sensata-Crydom, designed for DIN rail mounting applications requiring 4-32VDC input with isolated output capability. This module features a 4.5-30VDC output range and 32mA output current capacity, with integrated status LED indication. The product is currently obsolete, necessitating identification of functionally equivalent active alternatives to maintain system compatibility and ensure continued supply availability.

Substitute Part Grouping Explanation

Substitution eligibility for the 84115503 is determined by the following critical parameters:

• Input voltage range: 4-32VDC (must match or encompass)
• Output voltage range: Must accommodate system requirements
• Output current capacity: Minimum 32mA required
• DIN rail mount form factor: Required for mechanical compatibility
• Status LED functionality: Present in all alternatives
• Switching response times: Turn-on and turn-off characteristics

The two active substitute parts (DR-IDC5 and DRIDC24) maintain identical input voltage specifications and DIN rail mounting, with output voltage configurations optimized for specific application requirements. Both substitutes provide reduced switching times and active product status with current compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

DR-IDC5 Selection Criteria:

• Application requires 5VDC fixed output voltage
• System design accommodates 28mA output current (4mA reduction from original)
• Improved switching response times (1ms vs. 5-10ms) acceptable or beneficial
• RoHS3 compliance required
• Active product status with ongoing manufacturer support

DRIDC24 Selection Criteria:

• Application requires 24VDC fixed output voltage
• System design accommodates 28mA output current (4mA reduction from original)
• Improved switching response times (1ms vs. 5-10ms) acceptable or beneficial
• RoHS compliance required
• Active product status with ongoing manufacturer support

Both substitutes provide superior switching performance and active product lifecycle status compared to the obsolete 84115503. Selection between DR-IDC5 and DRIDC24 depends solely on the required output voltage specification for the target application.

Frequently Asked Questions (FAQ)

Q: Can DR-IDC5 or DRIDC24 directly replace 84115503 in existing designs? A: Direct replacement requires verification that the fixed output voltage (5VDC or 24VDC) matches the original application requirement. The 84115503 provides variable output (4.5-30VDC), while substitutes provide fixed voltage. Input voltage range (4-32VDC) and DIN rail mounting are identical.

Q: What is the impact of reduced output current (28mA vs. 32mA)? A: The 4mA reduction must be evaluated against actual system load requirements. If the original design operated below 28mA output current, substitution is compatible. If load exceeds 28mA, substitution is not suitable.

Q: How do the improved switching times affect system operation? A: DR-IDC5 and DRIDC24 provide faster response (1ms turn-on/off vs. 5-10ms). This improvement is generally beneficial for control applications and does not introduce compatibility issues with slower systems.

Q: Are there packaging differences between the main part and substitutes? A: The 84115503 uses standard packaging, while DR-IDC5 and DRIDC24 are supplied in bulk packaging. Both maintain identical DIN rail mount form factor and mechanical compatibility.

Q: What compliance certifications apply to each substitute? A: DR-IDC5 carries RoHS3 compliance. DRIDC24 carries RoHS compliance. Both are EAR99 classified. Verify compliance requirements for your specific application and regulatory jurisdiction.
